1 Claim. (Cl. 4-217) This invention relates to a ventilated toilet seat.

An object of this invention is to provide in combination an improved toilet seat with a suction means in the lower. side of the seat whereby the offensive odors may be withdrawn from the toilet bowl.

Another object of this invention is to provide an improved toilet seat which is so constructed that the bowl will be sealed against exhaust of odors when a person is seated thereon.

A further object of this invention is to provide a ventilated toilet seat wherein the suction duct forms the pivot means for the seat, and a suction element may be connected with either end of the pivot means.

A further object of this invention is to provide a ventilated toilet seat wherein the seat member is formed with raised anterior and posterior portions which assist in effecting a seal, and also prevent foul air, odor, and gases from escaping the bowl, and at the same time prevent vibrations and noise escaping.

Qther important objects of the invention are the provision of an improved device to prevent odors, foul air and gases escaping the bowl other than by suction, to eliminate the odor, foul air and gases by suction as well as providing the maximum in silencing and deadening noises by having a muflling effect. These objects are accomplished by the special construction of having two elevations on the top side of the toilet seat, one, the larger in the center on the anterior portion to prevent odors, foul air and gases to escape anterior the mons veneris and between the upper thighs or legs, and the other elevation in the center on the posterior portion to prevent the escape of odors, foul air and gases by fitting snugly across and between the posterior portion of the buttocks, whereby the lower portion of the torso or body of the toilet user and the tight fit of the toilet seat on the toilet bowl, a sealing gasket means being provided therebetween. effectively seals the bowl. There is also provided a recessed or cut away portion on the underneath and inside area of the seat on the posterior half to provide space for the collector. The collector is the terminal portion of the suction apparatus inside the seat to the right and left where the odors. gases, and foul air are picked up or collected by suction of a suction motor.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a plan view of a ventilated toilet seat constructed according to an embodiment of this invention,

Figure 2 is a sectional view taken on the line 22 of Figure 1,

Figure 3 is a fragmentary bottom plan, partly in section, of the rear portion of the seat,

Figure 4 is a fragmentary sectional view taken on the line 44 of Figure 1,

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 1,

Figure 6 is a fragmentary sectional view taken on the line 66 of Figure 1,

Figure 7 is a fragmentary sectional view taken on the line 77 of Figure 1.

Referring to the drawings, the numeral 10 designates generally a toilet seat of substantially ovoidal configura- 7 2,696,619 Patented Dec... 14, 1954 tion. The seat 10'is'pro'vided at the rear thereof with a raised portion 11, of substantially tri'angular cross-secti'onal configuration" or inverted" V=shape having smoothly rounded ends and top edge, adapted to engage between the buttocks for sealing the rear portion of the seat and the seat member 10 is also provided at the front thereof with an upstanding interiorly hollowed member 12 engageable between the thighs for assisting in sealing the forward or front portion of the seat.

The bottom of the seat member 10 on the inside of the inner margin 13 thereof is formed with a channel or groove 14, including a peripheral internal flange 14a which extends from the rear of the seat and merges with the hollow or cutout inner portion 15 of the front raised portion 12.

Member 12 is of substantially cup-shaped interior configuration and the rim 12a thereof is of arcuat'e configuration, including a rearwardly extending upper portion 12b in order closely to follow the body contour.

An arcuate suction tube 16 is disposed in the rear portion of the channel 14 and is formed with open forward ends which are cut off on an angle, as indicated at 17, to provide a relatively long entrance for the suction member 16.

A rearwardly projecting pipe 18 is seated in a groove 19a in the rear portion 19 of the seat 10 and communicates with the suction tube 16. The tube or pipe 18 is connected to the central branch 20 of a T 21 and the T 21 has threaded into the opposed branches thereof a pair of relatively short pipes 22 which provide pivot means, as will be hereinafter described.

One of the pipes 22 is adapted to have a cap 23 mounted thereon and the other of the pipes 22 is adapted to have a suction tube 24 mounted thereon and connected to a suction fan or the like.

The seat member 10 has extending rearwardly therefrom a pair of rods 25 formed with balls 26, having open ings 27 therethrough, within which the pipes 22 loosely engage. Supporting bearings 28 loosely engage about the pipes 22 outwardly from the balls 26 and are adapted to be secured in the conventional manner to the rear portion of the toilet bowl.

In order to provide a means whereby the bottom of the seat 10 may be sealed relative to the rim of the bowl, the seat member 10 is formed with a channel or groove 29 in the lower side thereof within which a rubber or resilient seal member 30 is seated. The seal member 30 is adapted to engage the rim of the bowl on the upper side thereof and thereby seal the seat member 10 relative to the bowl. Alternatively the groove 29 may be omitted and a sealing strip of rubber or felt may be secured directly to the underside of the seat as by gluing or tacking.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

A ventilated toilet seat comprising an ovoidal toilet seat member having an inwardly depressed portion of curved cross sectional area around the inner rim thereof, a posterior projection of inverted V-shape having a top portion of arcuate cross section adapted to seat 1n the crease between the buttocks to seal the posterior portion of the seat, an anterior raised inverted inwardly opening cup shaped portion having an inwardly convexed lnner margin adapted closely to engage the upper pubic region and together with concaved portions on opposite sldes of said convexed inner margin adapted to receive the inner sides of the thighs to seal the anterior portion of the seat, the engagement of the sides of the buttocks in sa d inwardly depressed portion sealing the upper side of said seat against the escape of gasses, a compresslble gasket on the underside of the seat tightly seating against the bowl rim to prevent the escape of gasses from the interior of the bowl beneath the seat, vents on the underside of the seat communicating with the bowl, and gas evacuating means connected to said vents.
